摘 要： Based on a linkage between rolling contact fatigue and structural fatigue, a new life theory for rolling bearings has been proposed using the three-parameter Weibull distribution function. A minimum life is introduced as the third parameter, which may be considered independent from the statistical strength of material. The following are the new findings: (1) Reliability functions and life equations were introduced for the rolling bearing races and the life test specimens made of the same material (JIS SUJ2/AISI 52100), and the linkage between them has successfully been established by using linkage factors. (2) The 90% load rating and rating life formulas for the races as well as for the whole bearing were developed. (3) Newly introduced 100% load rating and rating life formulas were postulated by introducing the minimum lives for the life tests and theoretical research. (4) For the ratios of each load rating between the test results on the grease-lubricated deep-groove ball bearings and the new life theory, the linkage factors were determined as β= 2.4 and β' = 2.16 for 90 and 100% load ratings, respectively. (5) A reduction factor λ for 100% load rating was determined as λ =β'/β = 0.9.

基于滚动接触疲劳与结构疲劳之间的关联，提出了一种采用三参数威布尔分布函数的滚动轴承寿命新理论。引入了最小寿命作为第三个参数，该参数可视为与材料统计强度无关。主要发现如下：（1）针对由相同材料（JIS SUJ2/AISI 52100）制成的滚动轴承滚道及寿命试验试样，建立了可靠性函数和寿命方程，并通过关联系数成功建立了二者之间的联系。（2）推导出了滚道及整个轴承的90%载荷额定值和额定寿命公式。（3）根据寿命试验和理论研究，提出了新的100%载荷额定值和额定寿命公式。（4）对于深沟球轴承在润滑脂润滑条件下试验结果与新寿命理论之间各载荷额定值的比值，经计算得出关联系数分别为β=2.4和β'=2.16，分别对应90%和100%的载荷额定值。(5) 对100%负载额定值的衰减系数λ确定为λ = β'/β = 0.9。
